Drastic effect of bidentate phosphine ligands on Pd-catalyzed hydroarylation of ethyl propiolate: a simple route to arylbutadienes.
Palladium complexes with bidentate phosphine ligands, Pd(dppe)(OAc)(2) and Pd(dppm)(OAc)(2), were found to be effective catalysts for reactions of simple arenes with ethyl propiolate, affording arylbutadiene derivatives selectively.
